I have used Elite Kura trainer fo 2 month this spring without any trouble. Connected to Zwift, Virtual Trainning and Garmin Edge 520 over ANT+. After few month break I restarted to train on Kura, same configurations, same connections, refreshing battery by pedaling ( more than 3 hours actuall )and connecting to USB power source. Kura connects, gives good values for cadence and speed but power sensor gives absurd values in thousand of watts (1000-8000W) and values are jumping in like 2 second intervals. I gets same behaviour with Garmin, Zwift and Rouvy. Of course Zwift and Rouvy switch power sensor off very soon as it considers these figures faulty. Thus I am not able to run on Zwift and Rouvy any more.Is it an option to reset or calibrate Kura and get back to real power values?

Thank you for advice! Adviced procedure worked for me.But still I am not sure how accurate are current power values.

I started calibration as adviced, app asked me to increase speed, I did my best, I guess I was riding like 700W but it was not enough for the app. Still asking to increase speed. So I had to cancel calibration because I was not able to ride more.Although above mentioned, power values seems to be real.So my question is whether such canceled calibration adjusted trainer correctly and whether declared power accuracy +/- 1% holds.
